BUMPER FOR AUTOMOBILES.

Application filed March 15, 1924.

To all whom it may concern Be it known that 1, JOHN I. ASNER, a citizen of the United States of America, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bumpers for Automobiles, of which the following is a specification.

This invention relates to bumpers for automobiles and other like vehicles and has particular reference to improvements shown on the bumpers illustrated in my copending application, Serial Number 681,831, filed December 20, 19251 @ne important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to improve the form of springs used herewith.

A third important object of the invention is to provide an improved arrangement of spring clips for such bumpers.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

1n the accompanying drawings like characters of reference indicate like parts in the several views, and:

Figure 1 is a perspective view illustrating a form of a double bumper constructed in accordance with this invention.

Figure 2 is a detail perspective of one member of a rear spring clip used herewith.

Figure 3 is a perspective view of the other member of said spring clip.

Figure & is a perspective view of the rear member of a front spring slip as used herewith.

Figure 5 is a perspective view of a single bumper constructed in accordance with this invention.

Figure 6 is a perspective view of a rear spring clip used with the single bumper.

F igure 7 is a detail cross section of a portion of Figure 1 showing the rear spring clip in position.

Figure 8 is a similar cross section of Figure 5.

In the forms of the invention shown in Figures 1 to 8 main bumper springs are provided, each of which consists of a single length of spring metal bar, having a straight Serial No. 699,458.

central portion 20 which constitutes the forward face of the bumper. Each end of each bar is bent back on the central portion in a reversed curve :21 and from the end of this reversed curve extends straight inwarlly toward the center as shown at 22 being bent forwardly and outwardly at the center by central curves or doubles 23. From the curve 28 the end of each bar extends outwardly and rearwardly so as to determine in a volute 24, the rear of which touches the straightportion 22 while the front engages against the rear side of the perspective straight portion 20.

In the form shown in Figure 1 two of these springs are employed and at the front the curves 23 are clipped to the middle of the straight portion QOby a special clip consisting of a body portion 25 extending between the two spring members and provided at its ends with vertical members 26 which engage in the curves or bends 23, said clip being further provided with a face plate 27 secured to the back plate by rivets or bolts 28. It will be seen that the rear member of this clip is of H-shape. The volutes 24% are secured to the straight portions 22 also by special clips and each of these clips consists of a vertically elongated hexagonal base 29 having at each side a lug 30 which fits between the two bumper springs. At the top and bottom of this face the clip extends forwardly over the top of the upper spring and bottom of the lower spring by means of lugs 31 and these lugs are provided with lips 32 which engage against the forward surface of the rear portion of the volutes 24. A cover plate 33 fits between the lugs 30 and the lips 32 and is held in position by means of a suitable bo t 34:.

In the form shown in Figure 5 the straight portion 20 is preferably reinforced by a flat bar 36 and this bar, the front portion 20, and the front parts of the bends 2 5 are held together by clips 37. In this single form the volute is held to the rear straight portion 22 by means of the clips such as are shown in Figure 6. These clips have an inverted U-shaped body portion 38, the legs of which have their extremities angularly disposed in downwardly and rearwardly directed parallel positions, such extremities being shown at 39, and being pro vided with alined bolt or rivet openings 40 through which pass the rivets or bolts a1.
